SHUTTLE-ACTION Fonl Looms.

To all whom t may concern: l

:Be 1t known that we, 'JOZEF yVVoJTI'AsI'E- wrczandJoHN ZAJAC., citizensof Austria,

residing at ,Chadwicks in the county of Oneida fand State of yNewYork,.ha\`fe vinvented Certain new andusefulImprovements .inShuttle-Actions -for Looms, ofv which the `following is aspecication,jreference being yhad therein to the accompanying drawing.

Our inventionrelatesfto a shuttle. action for looms and we declare thelfollowingto be .a full, clear, f concise and Iexact description.thereof sufficient to enable kanyone skilled .in theart to which itappertainsto .make vand use the same referencebeinghad Vtov-theaccompanayingdrawings in which likereference characters refer to, likeparts` throughlout the vspeciiication.

The object oftheeinvention is to provide a durable device for throwing`theshuttle .across the loom in the usual manner of A weaving. 'Intheconstruction of looms, heretofore, the mechanism for throwing the.shuttle across the loo-rn was under so'. great a strain thatfrthe partsin lconnection therewith .wore out 4very A quickly, .i therebynecessitatingvnew ones. y'This invention is designed to overcome thatserious defect by .transferring .the strain to levers o that l are movedalternately, whereby to `eilect. the .lac-

tuation of the shuttle. y

The object will- Albe understood by reierring to the drawings in which:
